Reduce Side Effects

A common side effect of antibiotics is diarrhea, which may be caused by the elimination of beneficial bacteria normally found in the colon. Controlled studies have shown that taking probiotic microorganisms—such as Lactobacillus casei, Lactobacillus acidophilus, Bifidobacterium longum, or Saccharomyces boulardii—helps prevent antibiotic-induced diarrhea.23

The diarrhea experienced by some people who take antibiotics also might be due to an overgrowth of the bacterium Clostridium difficile, which causes a disease known as pseudomembranous colitis. Controlled studies have shown that supplementation with harmless yeast—such as Saccharomyces boulardii24 or Saccharomyces cerevisiae (baker’s or brewer’s yeast)25—helps prevent recurrence of this infection. In one study, taking 500 mg of Saccharomyces boulardii twice daily enhanced the effectiveness of the antibiotic vancomycin in preventing recurrent clostridium infection.26 Therefore, people taking antibiotics who later develop diarrhea might benefit from supplementing with saccharomyces organisms.

Treatment with antibiotics also commonly leads to an overgrowth of yeast (Candida albicans) in the vagina (candida vaginitis) and the intestines (sometimes referred to as “dysbiosis”). Controlled studies have shown that Lactobacillus acidophilus might prevent candida vaginitis.27

Support Medicine

When applied to the skin, glycyrrhetinic acid (a chemical found in licorice (Glycyrrhiza glabra)) increases the activity of hydrocortisone.28 This effect might allow for less hydrocortisone to be used when combined with glycyrrhetinic acid, but further study is needed to test this possibility.29

Zinc and Biotin

Children with alopecia areata who supplemented 100 mg of zinc and 20 mg biotin each day, combined with topical clobetasol, showed more improvement compared to children who took oral corticosteroid drugs.30 Controlled research is needed to determine whether adding oral zinc and biotin to topical clobetasol therapy is more effective than clobetasol alone. However, until more information is available, caregivers should consider that children with alopecia who are currently taking oral corticosteroids might benefit from switching to supplements of zinc and biotin along with topical clobetasol.

Potential Negative Interaction

Explanation Required

In animal research, applying aloe (Aloe vera) gel topically along with a topical corticosteroid enhanced the hormone’s anti-inflammatory activity in the skin.31 No human research has investigated this effect.
